In Seawolf, aka RedHat 7.1, you are shipping libpcap 0.4, and tcpdump
3.4. The current shipping version of each of those are libpcap 0.6.2 and
tcpdump 3.6.2. The newer releases give you a lot of added functionality,
such as support for SMB and SNMP v2/v3 formatted printing.
Updating to libpcap 0.6.2 would also make it much easier to install snort
on a RedHat system. You should check the FAQ on www.snort.org, it
actually has a question that reads, "I've got RedHat and...", which is
answered by, "Check your version of libpcap."
